As shown in FIG. 4, the image display device 10 includes memories 31 a and 31 b, an adjustment unit 40, an input control unit 41, a first display control unit 42, and a second display control unit 43. The memories 31a and 31b are part of the storage area of the main memory 31 described above. The adjustment unit 40, the input control unit 41, the first display control unit 42, and the second display control unit 43 are realized by the CPU 30 executing the predetermined program.

The memories 31a and 31b temporarily store images captured by the left eye image capturing unit 18a and the right eye image capturing unit 18b, respectively. The memory 31a stores the left-eye image captured by the left-eye image capturing unit 18a, and the memory 31b stores the left-eye image captured by the right-eye image capturing unit 18b.

  In accordance with the output signal from the input control unit 41, the adjustment unit 40 displays the relative position, the relative size, and the relative size of both images when the left-eye image and the right-eye image are displayed on the display device. Adjust the rotation. The positions of the image for the left eye and the image for the right eye are represented as coordinate values (coordinate values of the XY coordinate system set internally) of the respective images. The X-axis direction of the XY coordinate system corresponds to the horizontal direction of the screen (screens of the stereoscopic image display device 11 and the flat image display device 12), and the Y-axis direction corresponds to the vertical direction of the screen. The relative positions of the left-eye image and the right-eye image are adjusted by changing the coordinate values in the horizontal direction (X direction) and / or vertical direction (Y direction) of the image center of each image. For example, the adjustment unit 40 adjusts the relative positions of the left-eye image and the right-eye image by moving the left-eye image and / or the right-eye image in the horizontal direction. The adjustment unit 40 adjusts the relative sizes of the left-eye image and the right-eye image by changing the size of the left-eye image and / or the right-eye image. For example, the adjustment unit 40 enlarges the left-eye image so that the left-eye image is relatively larger than the right-eye image. Further, the adjustment unit 40 adjusts the relative rotation (rotation angle) between the left-eye image and the right-eye image by rotating the left-eye image and / or the right-eye image around the respective image centers. For example, the adjustment unit 40 adjusts the relative rotation between the left-eye image and the right-eye image by rotating the left-eye image by a predetermined angle.

  The input control unit 41 outputs a control signal to the adjustment unit 40 according to the position detected by the touch panel 15. That is, the input control unit 41 performs an operation on a left-eye image and a right-eye image (an operation on a position adjustment bar 54 (see FIG. 5) described later), a left-eye image performed by the user according to the position detected by the touch panel 15. Alternatively, a rotation operation, an enlargement or reduction operation, or the like for the right eye image) is detected and transmitted to the adjustment unit 40 as a control signal. The input control unit 41 also determines the position of the position adjustment bar 54 displayed on the flat image display device 12, the position of the slider 55 of the position adjustment bar 54, and the zoom adjustment bar 56 according to the position detected by the touch panel 15. The position of the slider 57 is adjusted. Further, the input control unit 41 scrolls or zooms the stereoscopic image displayed on the stereoscopic image display device 11 according to the position detected by the touch panel 15 (details will be described later).

  The first display control unit 42 performs display control of the stereoscopic image display device 11. The first display control unit 42 causes the stereoscopic image display device 11 to display a stereoscopic image by combining the left-eye image and the right-eye image adjusted by the adjustment unit 40. For example, when the adjustment unit 40 shifts the positions of the left-eye image and the right-eye image by a predetermined amount in the left-right direction, the first display control unit 42 sets the position of the left-eye image and the right-eye image to the predetermined value. Shift left and right by the amount. Then, the first display control unit 42 generates a stereoscopic image by combining the two shifted images. For example, the first display control unit 42 divides the two shifted images into strips for each line in which the pixels are arranged vertically, and alternately arranges the striped strip images so that the two images are displayed. Synthesize. Then, the combined image data is output to the stereoscopic image display device 11. By viewing the displayed image through the parallax barrier, the stereoscopic image display device 11 alternately displays the right eye and the left eye for each line. Therefore, the right eye image and the left eye are displayed for the user's right eye. Can visually recognize the left-eye image. As a result, the stereoscopic image is displayed on the stereoscopic image display device 11. Further, the first display control unit 42 zooms or scrolls the stereoscopic image displayed on the stereoscopic image display device 11 based on the signal from the input control unit 41.

The second display control unit 43 performs display control of the flat image display device 12. The second display control unit 43 superimposes the left-eye image and the right-eye image adjusted by the adjustment unit 40 and causes the planar image display device 12 to display the superimposed planar image. For example, when the adjustment unit 40 shifts the positions of the left-eye image and the right-eye image by a predetermined amount in the left-right direction, the second display control unit 43 sets the positions of the left-eye image and the right-eye image to the predetermined Shift left and right by the amount. Then, the second display control unit 43 superimposes the two shifted images so as to be translucent, and causes the planar image display device 12 to display them in a planar manner. Therefore, the user can visually recognize both the left-eye image and the right-eye image, and can easily recognize how much the left-eye image and the right-eye image are shifted. The second display control unit 43 controls the display of the position adjustment bar 54 and the zoom adjustment bar 56 based on the signal from the input control unit 41.

(3D image adjustment operation)
Next, the adjustment of the stereoscopic image will be described with reference to FIGS. FIG. 5 is a diagram illustrating an example of images displayed on the screens of the stereoscopic image display device 11 and the flat image display device 12. In FIGS. 5 to 12, the portions not related to the description are not shown, and the screens of the stereoscopic image display device 11 and the flat image display device 12 are displayed relatively larger than actual. .

  As shown in FIG. 5, an image display area 50 is provided on the screen of the flat image display device 12. In the image display area 50, a left-eye image 51a and a right-eye image 51b are displayed. As shown in FIG. 5, the ratio of the horizontal width in the aspect ratio of the image display area 50 (the ratio between the horizontal length (horizontal width) and the vertical length (height)) is the left-eye image 51a and the right-eye image. It is larger than the width ratio in the aspect ratio of the image 51b. That is, the image display area 50 is a horizontally longer area than the left-eye image 51a and the right-eye image 51b.

  The left-eye image 51a is an image captured by the left-eye image capturing unit 18a, and the left-eye image 51a includes an imaging target image 52a and an imaging target image 53a. The imaging target image 52a and the imaging target image 53a are images obtained by imaging the imaging targets 52 and 53 existing in the real space by the left-eye image imaging unit 18a. The right eye image 51b is an image captured by the right eye image capturing unit 18b, and the right eye image 51b includes an imaging target image 52b and an imaging target image 53b. The imaging target image 52b and the imaging target image 53b are images obtained by imaging the imaging targets 52 and 53 existing in the real space by the right eye image imaging unit 18b. That is, the imaging target image 52a and the imaging target image 52b are images obtained by imaging the same imaging target 52. However, since the left-eye image 51a and the right-eye image 51b have parallax, the imaging target image 52a and the imaging target image 52b are not completely the same image. Similarly, the imaging target image 53a and the imaging target image 53b are images obtained by imaging the same imaging target 53. However, since the left-eye image 51a and the right-eye image 51b have parallax, the imaging target image 53a and the imaging target image 53b is not completely the same image.

  As shown in FIG. 5, the left-eye image 51 a and the right-eye image 51 b displayed on the screen of the flat image display device 12 are displayed in a semi-transparent and superimposed manner. A position adjustment bar 54 and a slider 55 are displayed on the screen of the flat image display device 12. A zoom adjustment bar 56 and a slider 57 are displayed on the screen of the flat image display device 12.

  On the other hand, a stereoscopic image 61 is displayed on the screen of the stereoscopic image display device 11. The stereoscopic image 61 is an image in which the left-eye image 51 a and the right-eye image 51 b are combined, and is an image that appears stereoscopic when the user views the stereoscopic image 61. The stereoscopic image 61 includes an imaging target image 62 and an imaging target image 63. The imaging target image 62 is an image obtained by imaging the imaging target 52 existing in the real space, and is an image that the user can see stereoscopically as shown in FIG. The imaging target image 62 is an image obtained by combining the imaging target image 52a of the left-eye image 51a and the imaging target image 52b of the right-eye image 51b. Similarly, the imaging target image 63 is an image obtained by imaging the imaging target 53 existing in the real space, and is an image that the user can see stereoscopically as shown in FIG. The imaging target image 63 is an image obtained by combining the imaging target image 53a of the left-eye image 51a and the imaging target image 53b of the right-eye image 51b.

  The position adjustment bar 54 is a user interface for the user to adjust the positions of the left-eye image 51a and the right-eye image 51b in the horizontal and vertical directions of the screen. The user can adjust the horizontal shift amount (relative position) of the left-eye image 51a and the right-eye image 51b by sliding the slider 55 of the position adjustment bar 54 in the horizontal direction while touching with the stick 16. . In addition, the user touches a predetermined position of the position adjustment bar 54 with the stick 16 to move the slider 55 to the touch position, and the lateral shift amount (relative to the left-eye image 51a and the right-eye image 51b). Position) can be adjusted. Although details will be described later, the stereoscopic effect of the stereoscopic image displayed on the stereoscopic image display device 11 is changed by this adjustment.

  In FIG. 5, the left-eye image 51a and the right-eye image 51b are displayed with a slight shift in the vertical and horizontal directions for the sake of explanation, but in actuality, the positions of the left-eye image 51a and the right-eye image 51b are displayed. Are matched (the image center of the left-eye image 51a and the image center of the left-eye image 51a are matched). However, the imaging target image 52a included in the left-eye image 51a and the imaging target image 52b included in the right-eye image 51b are different in position. Specifically, when the positions of the two images are matched and semi-transparent and superimposed, the imaging target image 52a included in the left-eye image 51a is on the right side of the imaging target image 52b included in the right-eye image 51b. It is shifted to. That is, the imaging target image 52a included in the left-eye image 51a is positioned relatively on the right side, and the imaging target image 52b included in the right-eye image 51b is positioned relatively on the left side. Therefore, the imaging target image 62 displayed on the stereoscopic image display device 11 seems to be positioned in front of the screen of the stereoscopic image display device 11 for the user (see FIG. 7 described later). In addition, the imaging target image 53a included in the left-eye image 51a is further shifted to the right side than the imaging target image 53b included in the right-eye image 51b. That is, the imaging target image 53a included in the left-eye image 51a is shifted to the right side, and the imaging target image 53b included in the right-eye image 51b is shifted to the left side. The deviation between the imaging target image 53a and the imaging target image 53b is larger than the deviation between the imaging target image 52a and the imaging target image 52b. Therefore, the imaging target image 63 displayed on the stereoscopic image display device 11 seems to be positioned in front of the imaging target image 62 for the user (see FIG. 7 described later).

  Next, adjustment of the horizontal position of the left-eye image 51a and the right-eye image 51b will be described with reference to FIG. FIG. 6 is a diagram showing how the user adjusts the slider 55 of the position adjustment bar 54 using the stick 16. In FIG. 6, the slider 55 ′ indicated by a broken line is the one before being adjusted (moved in the right direction of the screen) by the user, and the slider 55 indicated by the solid line is after being adjusted by the user. It is. In accordance with the movement of the slider 55 from the position P1 to the position P2, the left-eye image 51a and the right-eye image 51b displayed in the image display area 50 of the flat image display device 12 each move in the horizontal direction of the screen. . Specifically, the left-eye image 51a moves in the left direction of the screen, and the right-eye image 51b moves in the right direction of the screen. That is, when the slider 55 of the position adjustment bar 54 moves in the horizontal direction, the left-eye image 51a and the right-eye image 51b move in the lateral direction in the opposite directions by the amount corresponding to the movement amount of the slider 55 (shift). The shift amount between the left-eye image 51a and the right-eye image 51b changes. Note that only one of the left-eye image 51a and the right-eye image 51b moves according to the movement amount of the slider 55, thereby changing the shift amount between the left-eye image 51a and the right-eye image 51b. Also good.

When the slider 55 of the position adjustment bar 54 is positioned at a predetermined position (for example, the center of the movable range), the amount of deviation between the left-eye image 51a and the right-eye image 51b is zero (the left-eye image 51a The position of the image center coincides with the position of the image center of the right-eye image 51b). For example, as the slider 55 is slid from the center to the right, the shift amount between the images increases so that the left-eye image 51a moves to the left and the right-eye image 51b moves to the right. Thereby, as described later, the imaging target image 62 and the imaging target image 63 displayed on the stereoscopic image display device 11 are displayed.
Seems to move deeper in the screen. Conversely, as the slider 55 is slid from the center to the left, the absolute value of the shift amount between the images increases so that the left-eye image 51a moves to the right and the right-eye image 51b moves to the left (the shift in this case). The quantity is negative). As a result, as described later, the imaging target image 62 and the imaging target image 63 displayed on the stereoscopic image display device 11 appear to move toward the front of the screen.

  On the other hand, the stereoscopic image 61 displayed on the screen of the stereoscopic image display device 11 also changes according to the movement of the slider 55. When the slider 55 is moved, the horizontal positions of the left-eye image 51a visually recognized by the user's left eye and the right-eye image 51b visually recognized by the user's right eye displayed on the screen of the stereoscopic image display device 11 also change. To do. That is, similarly to the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12, the left-eye image 51a and the right-eye image 51b displayed on the stereoscopic image display device 11 correspond to the movement amount of the slider 55. Move horizontally by the specified amount. As a result, when the user views the stereoscopic image 61 after the slider 55 moves (position P2), the imaging target image 62 and the imaging target image 63 included in the stereoscopic image 61 are before the slider 55 moves (position P1). It seems to be located in the back direction of the screen. That is, as the slider 55 moves, the imaging target image 62 and the imaging target image 63 included in the stereoscopic image 61 appear to move in the depth direction of the screen.

  FIG. 7 is a diagram illustrating a state in which the positions of the imaging target image 62 (52) and the imaging target image 63 (53) that the user feels by changing the slider 55 of the position adjustment bar 54 are changed. FIG. 7 is a view of the user, the stereoscopic image display device 11, and the two imaging targets 52 and 53 (imaging target images 62 and 63) as viewed from above, and shows the positional relationship felt by the user. Before the slider 55 moves, the user feels that the imaging target image 62 and the imaging target image 63 are located in front of the screen of the stereoscopic image display device 11 (on the user side from the screen) (62 ′ and 63 ′). Appears to be present). More specifically, in the same manner as the positional relationship between the imaging target 52 and the imaging target 53 that exist in the real space, the user sets the imaging target image 63 ′ to the position in the near side of the screen relative to the imaging target image 62 ′ (user It feels as if it exists in a position close to On the other hand, according to the movement of the slider 55, the user captures the imaging target image 62 and the imaging target image 63 in the back direction of the screen of the stereoscopic image display device 11 (the direction perpendicular to the screen and the user's line of sight). It appears to move (in other words, the screen of the stereoscopic image display device 11 appears to move toward the user). More specifically, after the slider 55 moves, the user feels that the imaging target image 62 is positioned in the back direction of the screen and the imaging target image 63 is positioned near the screen. As described above, when the user moves the slider 55 to the right of the screen of the planar image display device 12, the imaging target image 62 (and 63) included in the stereoscopic image 61 is as if the screen of the stereoscopic image display device 11. It looks as if it has moved in the back direction (as it moves away from the back of the screen). On the other hand, when the user moves the slider 55 to the left, the imaging target image 62 (and 63) included in the stereoscopic image 61 is as if it has moved in the front direction of the screen (as if it jumped out of the screen). appear. That is, when the user adjusts the slider 55 of the position adjustment bar 54 in the horizontal direction, it seems to the user that the position of the imaging target included in the stereoscopic image 61 has changed. Therefore, the user can change the appearance of the stereoscopic image 61 by moving the slider 55 of the position adjustment bar 54 in the horizontal direction.

In addition, the user can display the desired imaging target included in the stereoscopic image 61 in an easy-to-view manner for himself / herself by moving the slider 55 of the position adjustment bar 54 in the horizontal direction. For example, as shown by the dotted line in FIG. 7, before the slider 55 is moved, the position of the imaging target image 63 visually recognized by the user is in front of the screen, and is a position (63 ′ of 63 ′) away from the screen. Position). On the other hand, the position of the imaging target image 62 visually recognized by the user is in front of the screen and is in the vicinity of the screen (position 62 ′). In this case, it is easy for the user to visually recognize the imaging target image 62 in three dimensions, but it is difficult to visually recognize the imaging target image 63 in three dimensions. This is because the image is actually displayed on the screen, so that the user focuses his eyes on the screen when trying to view the image. The imaging target image 62 ′ before movement that is visually recognized in the vicinity of the screen is easy to be viewed stereoscopically because the position in the direction perpendicular to the screen recognized by the user is close to the position where the eyes are in focus. On the other hand, the imaging target image 63 ′ before movement is difficult to view in three dimensions because the position in the direction perpendicular to the screen recognized by the user is different from the position where the eyes are in focus (the focus of the eyes is on the screen). If the captured image 63 ′ before moving is viewed when it is suitable, the image may appear blurred or cannot be recognized as a solid. In this case, the user can move the imaging target image 63 in the back direction of the screen by moving the slider 55 in the horizontal direction, and can move the imaging target image 63 to the vicinity of the screen. Therefore, the user can display the desired imaging target (imaging target image 63) included in the stereoscopic image 61 in an easy-to-view manner by moving the slider 55 in the horizontal direction.

  Note that the stereoscopic image 61 after adjusting the lateral displacement (position) shown in FIG. 6 is an image in which both end portions of the stereoscopic image 61 before adjustment shown in FIG. 6). For this reason, a part of the imaging target image 62 shown in FIG. 6 is not displayed. This is because the left-eye image 51a and the right-eye image 51b are shifted in the horizontal direction, thereby generating a portion where the two images do not overlap. When a stereoscopic image is displayed on the screen of the stereoscopic image display device 11 including a portion (non-overlapping area) where the left-eye image 51a and the right-eye image 51b do not overlap, a part of the stereoscopic image becomes a stereoscopic image, A part of the image has no stereoscopic effect. The display at this time is in a state such as “I can't see what I should see” or “I can see what I shouldn't see” for the viewer. For this reason, the image becomes uncomfortable for the user as a whole. Therefore, only a portion (overlapping region) where the left-eye image 51a and the right-eye image 51b overlap is synthesized and displayed on the screen of the stereoscopic image display device 11.

  Here, the “overlapping part” and “non-overlapping part” of the two images will be described with reference to FIG. FIG. 8 is a diagram for explaining an overlapping portion and a non-overlapping portion when the left-eye image 51a and the right-eye image 51b are overlapped. As illustrated in FIG. 8, the left-eye image 51a includes imaging target images 52a, 53a, and 58a. Similarly, the right-eye image 51b includes imaging target images 52b, 53b, and 58b. When these two images are shifted in the horizontal direction and overlapped, a portion where the two images overlap (overlapping region) and a portion where the two images do not overlap (non-overlapping region) are generated. The overlapping portion is a region R surrounded by a broken line of the superimposed images. The portion that does not overlap is a region other than the region R of the superimposed image. Only the region R is displayed on the screen of the stereoscopic image display device 11. In this case, when the user views the screen of the stereoscopic image display device 11, the user can visually recognize the imaging target image 58a with the left eye and can visually recognize the imaging target image 58b with the right eye. As a result, the user can recognize the imaging target image 58 three-dimensionally. Further, since the imaging target image 53b included in the right-eye image 51b is included in the region R, it is displayed on the screen of the stereoscopic image display device 11. On the other hand, since the imaging target image 53a included in the left-eye image 51a is not included in the region R, it is not displayed on the screen of the stereoscopic image display device 11. Therefore, when the user views the screen of the stereoscopic image display device 11, the user cannot visually recognize the imaging target image 53a with the left eye, but can visually recognize the imaging target image 53b with the right eye. This is a natural view for the user. That is, even when the user sees the real space, there is a parallax between the right eye and the left eye, and therefore, when a certain object is seen, it may be visible only to one eye. For example, when the user views the scenery outside the window, there is a portion that can be seen by the left eye even if the portion is invisible to the right eye, for example. However, if a portion that does not overlap is displayed on the screen, a portion (53a in FIG. 8) that cannot be seen by the user's eyes (the left eye in the example of FIG. 8) can be seen, resulting in an uncomfortable image for the user. End up. Therefore, by displaying only the overlapping portion on the stereoscopic image display device 11, it is possible to display an image that does not feel uncomfortable for the user.

  On the other hand, the entire left-eye image 51a and right-eye image 51b are displayed in the image display area 50 of the flat image display device 12 before and after adjustment. More specifically, a portion where the left-eye image 51 a and the right-eye image 51 b overlap and a portion where they do not overlap are displayed in the image display area 50 of the flat image display device 12. As described above, in the stereoscopic image display device 11, only a portion where the two images overlap is displayed so that the stereoscopic image does not feel uncomfortable for the user. On the other hand, since the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are visually recognized by both eyes of the user, the user can recognize the two images as separate images. For this reason, there is no sense of incongruity for the user even if the non-overlapping part is displayed as well as the overlapping part of the two images. Rather, the display including the non-overlapping portion allows the user to recognize the two images as different images, and to easily recognize the positional relationship between the two images. Therefore, the user can easily recognize the position of the imaging target image included in the two images. In addition, since it is displayed on the flat image display device 12 including the non-overlapping portion, the user can capture the imaging target existing in the non-overlapping portion (the imaging target is not displayed on the stereoscopic image display device 11 or is a stereoscopic image). Even if displayed on the display device 11, it can be visually recognized only by one eye of the user). For example, the imaging target image 53a included in the left-eye image 51a illustrated in FIG. 8 exists in a portion that does not overlap and is not visually recognized by the user's left eye. When moving the left-eye image 51a so that the imaging target image 53a can be visually recognized by the user's left eye, it is difficult for the user to adjust while viewing the stereoscopic image 61 displayed on the stereoscopic image display device 11. . That is, since the imaging target image 53a is not displayed on the stereoscopic image display device 11, the position cannot be recognized. However, since the non-overlapping part is also displayed on the flat image display device 12, the user can adjust the position of the imaging target image 53a while visually recognizing the imaging target image 53a included in the non-overlapping part. it can. For this reason, the user can adjust the position of the imaging target existing in the non-overlapping portion, and can easily display the desired imaging target in a three-dimensional manner.

  Further, since the user can adjust the positions of the left-eye image 51a and the right-eye image 51b while viewing the stereoscopic image 61 displayed on the stereoscopic image display device 11, the user can easily adjust the stereoscopic image. it can. As described above, when the user views the stereoscopic image 61 displayed on the stereoscopic image display device 11, it may be difficult for the user to visually recognize the imaging target image 63 'shown in FIG. When the user cannot visually recognize the imaging target image 63 ′, it is difficult to determine in which direction the left-eye image 51a and the right-eye image 51b should be adjusted only by looking at the stereoscopic image display device 11. It cannot be determined to which position in the direction perpendicular to the screen the image to be imaged 63 ′ should be moved). On the other hand, the left-eye image 51a and the right-eye image 51b are displayed on the flat image display device 12 so as to be semitransparent and superimposed. Accordingly, the user can easily recognize how far the imaging target images 53a and 53b included in the two images are apart by looking at the flat image display device 12. Accordingly, the user can bring the imaging target images 53a and 53b closer to each other while viewing the left eye image 51a and the right eye image 51b displayed on the flat image display device 12 (so that the imaging target images 53a and 53b overlap). The positions of the left-eye image 51a and the right-eye image 51b may be adjusted.

Further, the user visually recognizes the entire images of both the left-eye image 51a and the right-eye image 51b (the entire image including the overlapping portion and the non-overlapping portion) while viewing the left-eye image 51a and the right-eye image 51b. The position (lateral deviation) can be adjusted. Therefore, since the user can easily recognize the positional relationship between the two images, adjustment is easy. For example, after adjusting two images to view a certain imaging target in three dimensions, the user can easily adjust the image even when adjusting an image to view another imaging target in three dimensions. Can do. That is, since the entire images of both the left-eye image 51a and the right-eye image 51b are displayed on the flat image display device 12, the positional relationship between the two images can be easily recognized even after adjusting the positions of the two images. can do. Therefore, adjustment is easy.

  As described above, by moving the slider 55 of the position adjustment bar 54 in the horizontal direction, the images displayed on the stereoscopic image display device 11 and the flat image display device 12 change. Specifically, by adjusting the horizontal position of the left-eye image 51a and the right-eye image 51b, the user displays the imaging target included in the stereoscopic image so as to move in a direction perpendicular to the screen. be able to. The user can adjust the positions of the left-eye image 51 a and the right-eye image 51 b displayed on the flat image display device 12 while viewing the stereoscopic image 61 displayed on the stereoscopic image display device 11. Thereby, the user can easily adjust the appearance of the stereoscopic image.

  Next, the adjustment of the vertical position of the left-eye image 51a and the right-eye image 51b will be described with reference to FIG. FIG. 9 is a diagram showing how the position of the left-eye image 51a and the right-eye image 51b is adjusted using the position adjustment bar 54 in the vertical direction.

  As illustrated in FIG. 9, when the user touches the position adjustment bar 54 using the stick 16 and moves the stick 16 upward on the screen of the flat image display device 12, the position is moved with the movement of the touch position. The adjustment bar 54 also moves upward. The position adjustment bar 54 is movable in the vertical direction (vertical direction) of the screen, and the movable range of the position adjustment bar 54 (the range in which the position adjustment bar 54 moves) is determined in advance. The movable range in the vertical direction of the position adjustment bar 54 is set to be smaller than the movable range in the horizontal direction of the slider 55 of the position adjustment bar 54.

  When the position adjustment bar 54 moves in the vertical direction, the left-eye image 51a and / or the right-eye image 51b displayed in the image display area 50 of the flat image display device 12 also move in the vertical direction (vertical direction). For example, when the position adjustment bar 54 is moved upward on the screen, the left-eye image 51a (or right-eye image 51b) is also moved upward on the screen in accordance with the upward movement amount of the position adjustment bar 54. To do. Note that the left-eye image 51 a and the right-eye image 51 b displayed in the image display area 50 may be moved in the opposite directions in the vertical direction according to the vertical movement of the position adjustment bar 54, or by the stick 16. Only the selected image may be moved in the vertical direction.

  On the other hand, as the position adjustment bar 54 moves in the vertical direction, the appearance of the stereoscopic image 61 displayed on the screen of the stereoscopic image display device 11 also changes. For example, when the left-eye image 51a and the right-eye image 51b are greatly shifted in the vertical direction of the screen, when the user looks at the imaging target image 62 included in the stereoscopic image 61, the actual shape of the imaging target 52 is different. It may look like a shape or it may be difficult to see as a stereoscopic image. However, when the user adjusts the shift in the vertical position between the left-eye image 51a and the right-eye image 51b, it is possible to display an easy-to-see image having a stereoscopic effect on the stereoscopic image display device 11.

  As described above, by moving the position adjustment bar 54 in the vertical direction (vertical direction) of the screen of the flat image display device 12, the shift in the vertical position of the left-eye image 51a and the right-eye image 51b is adjusted. Can do. This vertical position shift is caused by a physical position shift between the left-eye image capturing unit 18a and the right-eye image capturing unit 18b. For example, when the left-eye image capturing unit 18a is slightly shifted in the vertical direction from the right-eye image capturing unit 18b due to manufacturing errors or the like (when shifted in the upward direction in FIG. 2), they are slightly shifted in the vertical direction. A captured image is captured. The user can adjust the vertical shift between the left-eye image 51a and the right-eye image 51b with the position adjustment bar 54.

Normally, the vertical shift between the left-eye image 51a and the right-eye image 51b is slight, and the user often performs only fine adjustment in the vertical direction. On the other hand, in order to move the imaging target included in the stereoscopic image in the back direction or the near side of the screen, the user slides the slider 55 in the horizontal direction, thereby shifting the left-eye image 51a and the right-eye image 51b in the horizontal direction. adjust. In other words, the vertical adjustment amount is usually smaller than the horizontal adjustment amount. Therefore, in the present embodiment, the movable range in the vertical direction of the position adjustment bar 54 is set to be smaller than the movable range in the horizontal direction of the slider 55 of the position adjustment bar 54. For this reason, the user can easily adjust the horizontal deviation of the left-eye image 51a and the right-eye image 51b, and can easily fine-tune the vertical deviation. That is, since the slider 55 has a large movable range in the horizontal direction and the position adjustment bar 54 has a small movable range in the vertical direction, the user can make a large adjustment in the horizontal direction and can only make a fine adjustment in the vertical direction. . Further, since the slider 55 is slid in the horizontal direction in the horizontal adjustment and the position adjustment bar 54 is moved in the vertical direction in the vertical adjustment, the above operations are intuitive and easy to understand for the user. It can be said. The vertical adjustment of the left-eye image 51a and the right-eye image 51b may be performed by a slider of an adjustment bar different from the position adjustment bar 54.

  Next, the zoom operation will be described with reference to FIG. FIG. 10 is a diagram illustrating a state in which the stereoscopic image 61 is enlarged using the zoom adjustment bar 56. As shown in FIG. 10, when the user touches the slider 57 of the zoom adjustment bar 56 using the stick 16 and moves the stick 16 to the right of the screen of the flat image display device 12, the slider 57 moves to the right. Move to. 57 'indicates the slider 57 before movement, and 57 indicates the slider 57 after movement. As the slider 57 moves, the stereoscopic image 61 displayed on the stereoscopic image display device 11 is enlarged. In FIG. 10, since the stereoscopic image 61 is enlarged, the imaging target images 62 and 63 included in the stereoscopic image 61 are also enlarged. Since the stereoscopic image 61 is enlarged larger than the screen of the stereoscopic image display device 11, only a part of the stereoscopic image 61 is displayed.

  On the other hand, the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are not enlarged as the slider 57 moves. A stereoscopic image display frame 59 indicated by a broken line is displayed in the image display area 50 of the flat image display device 12. The stereoscopic image display frame 59 indicates an area corresponding to the area of the stereoscopic image displayed on the stereoscopic image display device 11. As described above, even when the stereoscopic image displayed on the stereoscopic image display device 11 is enlarged, the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are not enlarged, but are displayed as a whole. Therefore, even when the stereoscopic image is enlarged, it is easy to adjust the positions of the left-eye image 51a and the right-eye image 51b (adjustment of the horizontal and vertical positions using the position adjustment bar 54). That is, since the entire left-eye image 51a and right-eye image 51b are displayed on the flat image display device 12, the user can easily grasp the positional relationship between these images.

  Next, the scroll operation will be described with reference to FIG. FIG. 11 is a diagram illustrating how the stereoscopic image 61 is scrolled by a touch operation. As shown in FIG. 11, when the user moves the left-eye image 51 a or the right-eye image 51 b displayed on the flat image display device 12 on the screen while touching with the stick 16, the stereoscopic image display device 11. The three-dimensional image 61 is scrolled. For example, when the user uses the stick 16 to move the left-eye image 51a or the right-eye image 51b to the left while touching, the stereoscopic image 61 is scrolled to the right (the imaging target image 62 included in the stereoscopic image 61). Move to the left). The image after the stereoscopic image 61 is scrolled is displayed on the screen of the stereoscopic image display device 11 of FIG. Since the stereoscopic image 61 is scrolled in the right direction, the imaging target image 62 included in the stereoscopic image 61 moves to the left from the center of the screen, and a part of the imaging target image 63 is not displayed. Note that the user can scroll the stereoscopic image 61 in an arbitrary direction on the screen by the scroll operation.

On the other hand, the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are not scrolled by the scroll operation (the operation of moving the screen in the right direction while touching). The stereoscopic image display frame 59 is displayed in the image display area 50 of the flat image display device 12. As described above, even when the stereoscopic image displayed on the stereoscopic image display device 11 is scrolled, the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are not scrolled. Therefore, it is easy to adjust the positions of the left-eye image 51a and the right-eye image 51b (adjustment of the horizontal and vertical positions using the position adjustment bar 54). That is, since the entire left-eye image 51a and right-eye image 51b are displayed on the flat image display device 12, the user can easily grasp the positional relationship between these images.

  Next, rotation and size change of the left-eye image 51a or the right-eye image 51b will be described with reference to FIG. FIG. 12 is a diagram illustrating how the stereoscopic image is adjusted by rotating or enlarging the right-eye image 51b. When the user moves a predetermined position of the left-eye image 51a or the right-eye image 51b displayed on the flat image display device 12 while touching with the stick 16, the left-eye image 51a or the right-eye image 51b is rotated. To do. For example, as shown in FIG. 12, when the user operates to rotate the right eye image 51b (moving in the direction of arrow A in FIG. 12) while touching the vertex V1 of the right eye image 51b, The image 51b rotates. For example, when the user moves the stick 16 in the diagonal direction of the right eye image 51b while moving the vertex V1 of the right eye image 51b (moves in the direction of arrow B in FIG. 12), the right eye image 51b is Expanding.

  On the other hand, with the rotation or enlargement of the right-eye image 51b, the appearance of the stereoscopic image 61 displayed on the screen of the stereoscopic image display device 11 also changes. For example, when the right-eye image 51b is rotated by a predetermined angle with respect to the left-eye image 51a (more precisely, the imaging target image 52b included in the right-eye image 51b is captured in the left-eye image 51a). When the user looks at the imaging target image 62 included in the stereoscopic image 61, it looks like a shape different from the actual imaging target 52 or a stereoscopic image. It may be difficult to see as. The cause of such rotation may be an error during manufacturing. For example, the left-eye image capturing unit 18a may be rotated at a predetermined angle during manufacture. Therefore, the user can adjust the relative rotation angle of the left-eye image 51a and the right-eye image 51b by rotating the left-eye image 51a or the right-eye image 51b. As a result, the user can cause the stereoscopic image display device 11 to display an easy-to-see image having a stereoscopic effect.

  Further, for example, when the right-eye image 51b is smaller than the left-eye image 51a (more precisely, the imaging target image 52b included in the right-eye image 51b is more than the imaging target image 52a included in the left-eye image 51a. When the user looks at the imaging target image 62 included in the stereoscopic image 61, the user may see a shape different from the actual imaging target 52 or may be difficult to see as a stereoscopic image. Such a difference in size may be caused by a state at the time of imaging (for example, a difference in operation of zoom mechanisms of the left-eye image capturing unit 18a and the right-eye image capturing unit 18b). The user can adjust the relative sizes of the left-eye image 51a and the right-eye image 51b by enlarging or reducing the left-eye image 51a or the right-eye image 51b by the above-described operation. As a result, the user can cause the stereoscopic image display device 11 to display an easy-to-see image having a stereoscopic effect.

(Details of image display control processing)
Next, details of the image display control process according to the present embodiment will be described with reference to FIGS. 13 to 18. First, main data stored in the main memory 31 in the image display control process will be described. FIG. 13 is a diagram showing a memory map of the main memory 31 of the image display device 10. As shown in FIG. 13, the main memory 31 is provided with a data storage area 70. In the data storage area 70, left-eye image position data 71, right-eye image position data 72, current touch position data 73, previous touch position data 74, position adjustment data 75, zoom adjustment data 76, stereoscopic image display frame data 77, and the like. Is memorized. In addition to these data, the main memory 31 stores a program for executing the image display control process, image data for the left eye, image data for the right eye, image data for the position adjustment bar, image data for the zoom adjustment bar, and the like. Is done.

  The left-eye image position data 71 is data indicating the display position of the left-eye image 51a, and is data indicating the coordinate value of the image center of the left-eye image 51a. The right-eye image position data 72 is data indicating the display position of the right-eye image 51b, and is data indicating the coordinate value of the image center of the right-eye image 51b.

  The current touch position data 73 is data indicating the coordinate value of the touch position detected by the touch panel 15 in the current frame. When the touch position is not detected in the current frame, the current touch position data 73 stores a value indicating that the touch position is not detected. The immediately preceding touch position data 74 is data indicating coordinate values detected by the touch panel 15 in the immediately preceding frame. When the touch position is not detected in the immediately preceding frame, the previous touch position data 74 stores a value indicating that the touch position has not been detected.

  The position adjustment data 75 is data related to the position adjustment bar 54. Specifically, the position adjustment data 75 includes data indicating the coordinate value of the display position of the position adjustment bar 54 and data indicating the position of the slider 55 on the position adjustment bar 54.

  The zoom adjustment data 76 is data relating to the zoom adjustment bar 56 and is data indicating the position of the slider 57 on the zoom adjustment bar 56.

  The stereoscopic image display frame data 77 is data indicating the position and size of the stereoscopic image display frame 59 displayed on the planar image display device 12.

  Next, details of the image display control process will be described with reference to FIG. FIG. 14 is a main flowchart showing details of the image display control process according to the first embodiment. When the power of the image display device 10 is turned on, the CPU 30 of the image display device 10 executes a startup program stored in the ROM 32, whereby each unit such as the main memory 31 is initialized. Next, the image display control program stored in the ROM 32 is read into the main memory 31, and the CPU 30 starts executing the program. Further, the left-eye image 51 a and the right-eye image 51 b stored in the storage data memory 34 are read into the main memory 31. The flowchart shown in FIG. 14 is a flowchart showing processing performed after the above processing is completed. In FIG. 14, the description of processing not directly related to the present invention is omitted. Further, the processing loop of step S1 to step S8 shown in FIG. 14 is repeatedly executed for each frame (for example, 1/30 second, referred to as frame time).

  First, in step S <b> 1, the CPU 30 detects a touch on the touch panel 15. When the touch on the touch panel 15 is performed, the CPU 30 stores the detected touch position in the main memory 31 as the current touch position data 73, and then executes the process of step S2. On the other hand, when the touch on the touch panel 15 is not performed, the CPU 30 stores a value indicating that the touch position is not detected as the current touch position data 73 in the main memory 31, and then executes the process of step S6. To do.

In step S2, the CPU 30 executes a position adjustment process. In step S2, the positions of the left-eye image 51a and the right-eye image 51b are adjusted based on the detected touch position. Details of the position adjustment processing in step S2 will be described with reference to FIG. FIG. 15 is a flowchart showing details of the position adjustment process (step S2).

  In step S <b> 11, the CPU 30 determines whether or not the current touch position is within the display area of the position adjustment bar 54. Specifically, the CPU 30 refers to the current touch position data 73 in the main memory 31 and acquires the current touch position (the touch position detected in step S1 of the current processing loop). Next, the CPU 30 refers to the position adjustment data 75 and the acquired current touch position is within the display area of the position adjustment bar 54 (area where the position adjustment bar 54 is displayed on the screen of the flat image display device 12). It is determined whether or not it exists. If the determination result is affirmative, the CPU 30 next executes a process of step S12. On the other hand, if the determination result is negative, the CPU 30 next executes a process of step S14.

  In step S12, the CPU 30 moves the slider 55 of the position adjustment bar 54 to the current touch position. In step S12, the slider 55 of the position adjustment bar 54 is moved laterally on the position adjustment bar 54. Specifically, the CPU 30 calculates a position on the position adjustment bar 54 corresponding to the current touch position and stores it in the position adjustment data 75 of the main memory 31. Next, the CPU 30 executes the process of step S13.

  In step S <b> 13, the CPU 30 sets a displacement amount in the horizontal direction. Specifically, the CPU 30 determines the horizontal direction of the left-eye image 51a and the right-eye image 51b (left and right (X-axis) direction of the screen) based on the position of the slider 55 on the position adjustment bar 54 calculated in step S12. Is calculated and stored in the main memory 31. When the slider 55 is present at a predetermined distance from the left end of the position adjustment bar 54, the CPU 30 sets the lateral displacement amount according to the predetermined distance. The amount of shift in the horizontal direction is a shift in coordinate values (difference in X coordinate values) regarding the X axis between the image center of the left-eye image 51a and the image center of the right-eye image 51b. For example, the CPU 30 sets the lateral shift amount when the slider 55 is present at the position P0 of the position adjustment bar 54 (for example, the center position of the position adjustment bar 54) to 0, and the slider 55 is located on the right side of the position P0. If present, the amount of lateral displacement is positive. On the other hand, for example, when the slider 55 exists on the left side of the position P0, the CPU 30 sets the lateral shift amount to be negative. Note that when the amount of shift in the horizontal direction is positive, the left-eye image 51a is positioned on the left side of the screen relative to the right-eye image 51b. When the lateral shift amount is negative, the left-eye image 51a is positioned on the right side of the screen relative to the right-eye image 51b. Next, the CPU 30 ends the position adjustment process.

  On the other hand, in step S <b> 14, the CPU 30 determines whether or not the touch position in the immediately preceding frame is within the display area of the position adjustment bar 54. The touch position in the immediately preceding frame is the touch position detected in step S1 in the processing loop immediately before the current processing loop. Specifically, the CPU 30 refers to the previous touch position data 74 in the main memory 31 and determines whether or not the previous touch position exists within the display area of the position adjustment bar 54. If the determination result is affirmative, the CPU 30 next executes a process of step S15. On the other hand, when the determination result is negative, the CPU 30 ends the position adjustment process.

  In step S <b> 15, the CPU 30 determines whether or not the current touch position is within the movable range of the position adjustment bar 54. The position adjustment bar 54 is movable in the vertical direction (vertical direction) of the screen within a predetermined range. Therefore, in step S15, it is determined whether or not the current touch position is within this movement range. If the determination result is affirmative, the CPU 30 next executes a process of step S16. On the other hand, when the determination result is negative, the CPU 30 ends the position adjustment process.

In step S16, the CPU 30 moves the position adjustment bar 54 to the current touch position. In step S16, the position adjustment bar 54 is moved in the vertical direction (vertical direction) of the screen. Specifically, the CPU 30 calculates a movement vector indicating the movement of the position adjustment bar 54 in the vertical (Y-axis) direction of the screen based on the current touch position indicated by the current touch position data 73. For example, the CPU 30 calculates an intersection between a line segment passing through the current touch position and parallel to the Y axis and the display area of the position adjustment bar 54, and calculates a vector from the calculated intersection toward the current touch position as the movement vector. To do. Then, the CPU 30 calculates the position of the position adjustment bar 54 by adding the calculated movement vector to the position vector indicating the display position of the position adjustment bar 54 indicated by the position adjustment data 75. The CPU 30 stores the calculated position of the position adjustment bar 54 in the main memory 31 as position adjustment data 75. Next, the CPU 30 executes the process of step S17.

  In step S <b> 17, the CPU 30 sets the amount of displacement in the vertical direction. Specifically, based on the position of the position adjustment bar 54 calculated in step S16, the CPU 30 determines the amount of shift in the vertical direction (up and down (Y axis) direction of the screen) between the left-eye image 51a and the right-eye image 51b. Calculate and store in the main memory 31. More specifically, the CPU 30 calculates the amount of positional shift in the vertical direction according to the coordinate value of the Y axis of the position adjustment bar 54. The amount of shift in the vertical direction is a shift in coordinate values (difference in Y coordinate values) regarding the Y axis between the image center of the left-eye image 51a and the image center of the right-eye image 51b. For example, the CPU 30 sets the vertical shift amount when the position adjustment bar 54 is present at a predetermined position (for example, the center of the position adjustment bar 54 in the vertical movable range) to 0 above the predetermined position. When the adjustment bar 54 exists, the amount of shift in the vertical direction is positive. On the other hand, for example, when the position adjustment bar 54 exists below the predetermined position, the CPU 30 sets the amount of shift in the vertical direction to be negative. When the amount of shift in the vertical direction is positive, the left-eye image 51a is positioned on the upper side of the screen relative to the right-eye image 51b. When the amount of shift in the vertical direction is negative, the left-eye image 51a is positioned on the lower side of the screen than the right-eye image 51b. Next, the CPU 30 ends the position adjustment process.

  Returning to FIG. 14, after the process of step S <b> 2, the CPU 30 next executes the process of step S <b> 3.

  In step S3, the CPU 30 executes rotation and size change processing. In step S3, based on the touch position detected in step S1, the left-eye image 51a or the right-eye image 51b is rotated, or the size of the left-eye image 51a or the right-eye image 51b is changed. Details of the rotation and size change processing in step S3 will be described with reference to FIG. FIG. 16 is a flowchart showing details of the rotation and size change processing (step S3).

  In step S21, the CPU 30 determines whether or not the touch position in the immediately preceding frame is the vertex of the left-eye image 51a or the right-eye image 51b. Specifically, the CPU 30 refers to the previous touch position data 74 and determines whether or not the previous touch position is within a predetermined region including the vertex of the left-eye image 51a or the right-eye image 51b. If the determination result is affirmative, the CPU 30 next executes a process of step S22. On the other hand, when the determination result is negative, the CPU 30 ends the rotation and size change processing.

  In step S22, the CPU 30 calculates a vector from the touch position in the immediately previous frame to the current touch position. Specifically, the CPU 30 refers to the current touch position data 73 and the previous touch position data 74, calculates a vector having the immediately previous touch position as the start point and the current touch position as the end point, and stores the vector in the main memory 31. . Next, the CPU 30 executes the process of step S23.

In step S23, the CPU 30 determines whether or not the distance between the touch position in the immediately previous frame and the current touch position is equal to or less than a threshold value. The amount of change in the amount of rotation or size of the image (left-eye image 51a or right-eye image 51b) selected by the immediately previous touch position is limited by the process in step S23. Specifically, the CPU 30 determines whether or not the magnitude of the vector calculated in step S22 is equal to or smaller than a predetermined threshold value. If the determination result is affirmative, the CPU 30 next executes a process of step S24. On the other hand, when the determination result is negative, the CPU 30 ends the rotation and size change processing.

  In step S24, the CPU 30 rotates or changes the size of the right-eye image or the left-eye image according to the calculated vector. Specifically, the CPU 30 rotates the image selected by the immediately previous touch position or changes the size of the selected image based on the direction and size of the vector calculated in step S22. For example, when the calculated vector direction is the diagonal direction of the selected image (when it is equal to or smaller than a predetermined angle), the CPU 30 enlarges the selected image according to the size of the vector. Here, the diagonal direction indicates a direction from the image center of the selected image toward the vertex designated by the immediately previous touch position. For example, when the calculated vector direction is opposite to the diagonal direction, the CPU 30 reduces the selected image. In addition, for example, when the calculated vector direction is perpendicular to the diagonal direction (in a range of a predetermined angle), the CPU 30 displays the selected image around the center of the image according to the size of the vector. Rotate to Next, the CPU 30 ends the rotation and size change processing.

  Returning to FIG. 14, after the process of step S3, the CPU 30 next executes a process of step S4.

  In step S4, the CPU 30 executes zoom processing. In step S4, the stereoscopic image 61 displayed on the stereoscopic image display device 11 is zoomed (enlarged or reduced) based on the touch position detected in step S1. Details of the zoom process in step S4 will be described with reference to FIG. FIG. 17 is a flowchart showing details of the zoom process (step S4).

  In step S <b> 31, the CPU 30 determines whether or not the current touch position is within the display area of the zoom adjustment bar 56. Specifically, the CPU 30 refers to the current touch position data 73 of the main memory 31 and displays the current touch position on the display area of the zoom adjustment bar 56 (the zoom adjustment bar 56 is displayed on the screen of the flat image display device 12. It is determined whether or not it exists in the area). If the determination result is affirmative, the CPU 30 next executes a process of step S32. On the other hand, if the determination result is negative, the CPU 30 ends the zoom process.

  In step S32, the CPU 30 moves the slider 57 of the zoom adjustment bar 56 to the current touch position. In step S32, the slider 57 of the zoom adjustment bar 56 is moved in the horizontal direction on the zoom adjustment bar 56. Specifically, the CPU 30 calculates a position on the zoom adjustment bar 56 corresponding to the current touch position and stores it in the zoom adjustment data 76 of the main memory 31. Next, the CPU 30 executes the process of step S33.

  In step S <b> 33, the CPU 30 performs zoom setting for the stereoscopic image 61. The process of step S33 is a setting process for zooming the stereoscopic image 61 displayed on the stereoscopic image display device 11 in step S6 described later. Specifically, the CPU 30 determines the degree of enlargement or reduction of both the left-eye image 51 a and the right-eye image 51 b according to the position of the slider 57 of the zoom adjustment bar 56 and stores it in the main memory 31. Next, the CPU 30 executes the process of step S34.

In step S <b> 34, the CPU 30 sets the stereoscopic image display frame 59. Specifically, the CPU 30 calculates the area of the stereoscopic image 61 displayed on the stereoscopic image display device 11 based on the zoom setting of the stereoscopic image 61 in step S33. That is, the CPU 30 calculates the position and size of the stereoscopic image display frame 59 and stores them in the main memory 31 as stereoscopic image display frame data 77. The stereoscopic image display frame 59 is a frame displayed in the image display area 50 of the planar image display device 12, and the left-eye image 51 a and the right-eye image corresponding to the region of the stereoscopic image 61 displayed on the stereoscopic image display device 11. The region 51b is shown. When the stereoscopic image 61 is enlarged by zooming, only a part of the left-eye image 51a and the right-eye image 51b may be displayed on the stereoscopic image display device 11. Even when the stereoscopic image 61 is enlarged by zooming, the stereoscopic image display frame 59 is not displayed when the left-eye image 51a and the right-eye image 51b are all displayed on the stereoscopic image display device 11. Next, the CPU 30 ends the zoom process.

  Returning to FIG. 14, after the process of step S4, the CPU 30 next executes the process of step S5.

  In step S5, the CPU 30 executes a scroll process. In step S5, the stereoscopic image 61 displayed on the stereoscopic image display device 11 is scrolled based on the touch position detected in step S1. Details of the scroll processing in step S5 will be described with reference to FIG. FIG. 18 is a flowchart showing details of the scroll process (step S5).

  In step S41, the CPU 30 determines whether or not the touch position in the immediately preceding frame is within the display area of the left-eye image 51a or the right-eye image 51b. Specifically, the CPU 30 refers to the previous touch position data 74 and determines whether or not the previous touch position is within the display area of the left-eye image 51a or the right-eye image 51b. If the determination result is affirmative, the CPU 30 next executes a process of step S42. On the other hand, when the determination result is negative, the CPU 30 ends the scroll process.

  In step S42, the CPU 30 calculates a vector from the touch position in the immediately previous frame to the current touch position. Specifically, the CPU 30 refers to the current touch position data 73 and the previous touch position data 74, calculates a vector having the immediately previous touch position as the start point and the current touch position as the end point, and stores the vector in the main memory 31. . Next, the CPU 30 executes the process of step S43.

  In step S43, the CPU 30 determines whether or not the distance between the touch position in the immediately previous frame and the current touch position is equal to or less than a threshold value. The scroll amount of the stereoscopic image 61 is limited by the process of step S43. Specifically, the CPU 30 determines whether or not the magnitude of the vector calculated in step S42 is equal to or smaller than a predetermined threshold value. If the determination result is affirmative, the CPU 30 next executes a process of step S44. On the other hand, when the determination result is negative, the CPU 30 ends the scroll process.

  In step S <b> 44, the CPU 30 sets the scroll direction and scroll amount of the stereoscopic image 61 displayed on the stereoscopic image display device 11. Specifically, the CPU 30 determines the direction opposite to the vector direction calculated in step S 42 as the scroll direction and stores it in the main memory 31. Thereby, the imaging target image included in the stereoscopic image 61 moves in the direction in which the user moves the stick 16. Further, the CPU 30 determines a scroll amount according to the vector size calculated in step S <b> 42 and stores it in the main memory 31. Next, the CPU 30 executes the process of step S45.

In step S45, the CPU 30 sets the stereoscopic image display frame 59. The process of step S45 is the same as the process of step S34 described above. Specifically, the CPU 30 calculates the area of the stereoscopic image 61 displayed on the stereoscopic image display device 11 based on the scroll setting of the stereoscopic image 61 in step S44. That is, the CPU 30 calculates the position of the stereoscopic image display frame 59 and stores it in the main memory 31 as stereoscopic image display frame data 77. Next, the CPU 30 ends the scroll process.

  Returning to FIG. 14, after the process of step S5, the CPU 30 next executes the process of step S6.

  In step S <b> 6, the CPU 30 displays the stereoscopic image 61 on the stereoscopic image display device 11. In step S6, the left-eye image 51a and the right-eye image 51b adjusted in steps S2 to S5 are displayed on the stereoscopic image display device 11, whereby the stereoscopic image 61 is displayed. Specifically, the CPU 30 combines the positions of the left-eye image 51a and the right-eye image 51b by shifting the horizontal and vertical positions set in the process of step S2. Further, the CPU 30 synthesizes the left-eye image 51a and the right-eye image 51b using the image (left-eye image 51a or right-eye image 51b) that has been rotated or resized in step S3. More specifically, the CPU 30 divides the two images adjusted in step S2 or S3 into strips for each line in which pixels are arranged vertically, and alternately arranges the striped images. Thus, the two images are synthesized. Further, the CPU 30 sets the display area based on the zoom setting set in the zoom process in step S4 or the scroll setting set in the scroll process in step S5. For example, when the zoom setting is performed in step S4, the CPU 30 sets a display area according to the determined degree of enlargement or reduction, and sets the areas of the left-eye image 51a and the right-eye image 51b corresponding to the display area. Enlarge or reduce (digital zoom). Further, for example, when the scroll setting is made in step S5, the CPU 30 sets the display area based on the scroll direction and the scroll amount. Note that, when the left-eye image 51a and the right-eye image 51b adjusted in steps S2 to S5 are overlapped, only the overlapping region is set as the display region. Then, the CPU 30 displays the stereoscopic image by causing the stereoscopic image display device 11 to display the display area of the synthesized image. Next, the CPU 30 executes the process of step S7.

  In step S <b> 7, the CPU 30 displays the left-eye image 51 a and the right-eye image 51 b on the flat image display device 12. In step S7, the left-eye image 51a and the right-eye image 51b adjusted in steps S2 to S5 are displayed on the flat image display device 12. Specifically, the CPU 30 shifts the positions of the left-eye image 51a and the right-eye image 51b by the horizontal and vertical position shift amounts set in the process of step S2, and makes the two images translucent. Overlapping. Then, the CPU 30 displays the superimposed image in the image display area 50 of the flat image display device 12. Further, the CPU 30 superimposes the left-eye image 51a and the right-eye image 51b in a translucent manner using the image (left-eye image 51a or right-eye image 51b) that has been rotated or resized in step S3. Then, the CPU 30 causes the flat image display device 12 to display the superimposed image. Here, the image display area 50 of the flat image display device 12 is smaller than the screen of the stereoscopic image display device 11. Therefore, the CPU 30 reduces the left-eye image 51a and the right-eye image 51b according to the size ratio between the image display area 50 and the screen of the stereoscopic image display device 11, and displays the reduced image on the flat image display device 12. In addition, the CPU 30 causes the flat image display device 12 to display the stereoscopic image display frame 59 set in the zoom process (S34) in step S4 or the scroll process (S45) in step S5. As described above, even if the stereoscopic image 61 displayed on the stereoscopic image display device 11 is zoomed or scrolled, the image displayed on the flat image display device 12 is not zoomed or scrolled. That is, even when the entire stereoscopic image 61 is not displayed on the stereoscopic image display device 11 by zooming or scrolling, the entire left-eye image 51a and right-eye image 51b are displayed on the planar image display device 12. Thereby, even when zoomed or scrolled, the user can adjust the image while confirming the entire left-eye image 51a and right-eye image 51b. Next, the CPU 30 executes the process of step S8.

In step S8, the CPU 30 determines whether or not the adjustment is finished. For example, the CPU 30 determines whether or not a predetermined operation has been performed by the user (for example, whether or not a button or the like disposed on the lower housing 13b (not shown) has been pressed). If the determination result is negative, the CPU 30 next executes the process of step S1. If the determination result is affirmative, the CPU 30 ends the process shown in FIG. The image display control process according to the present embodiment is thus completed.

  Note that the above-described processing contents, processing order, and the like are merely examples. That is, the position adjustment process, rotation, size change process, and the like are merely specific examples, and the relative positions, sizes, and rotations of the left-eye image 51a and the right-eye image 51b are adjusted in any way. Good. In addition, the order of the processing may be any order.

  As described above, the user can adjust the appearance of the stereoscopic image 61 by adjusting the position, size, and rotation of the left-eye image 51a and the right-eye image 51b. The user can adjust the position, size, and rotation of the left-eye image 51 a and the right-eye image 51 b on the screen of the flat image display device 12 while viewing the stereoscopic image 61 displayed on the stereoscopic image display device 11. . For this reason, the user can easily adjust the appearance of the stereoscopic image 61.

  Note that the left-eye image 51 a and the right-eye image 51 b captured by another device may be read into the image display device 10 via the storage data memory 34. Further, the left-eye image 51 a and the right-eye image 51 b captured by another device may be provided to the image display device 10 via the communication module 35.

  Further, information indicating the adjustment amount of the position, size, and rotation of the left-eye image 51a and the right-eye image 51b adjusted in steps S2 and S3 is stored together with the image data of the left-eye image 51a and the right-eye image 51b. The data may be stored in the data memory 34. The information may be stored as part of the image data of the left-eye image 51a and the right-eye image 51b. Then, the storage data memory 34 is connected to another device different from the image display device 10, and the three-dimensional data adjusted using the image data stored in the storage data memory 34 and the information indicating the adjustment amount are used. An image may be displayed on the screen of the other device.

  In the above embodiment, even when the stereoscopic image is zoomed or scrolled, the planar images (the left-eye image 51a and the right-eye image 51b) displayed on the planar image display device 12 are not zoomed or scrolled. . In another embodiment, when the stereoscopic image is zoomed or scrolled, the planar image displayed on the planar image display device 12 may be zoomed or scrolled. That is, in another embodiment, a part of the left-eye image 51a and the right-eye image 51b displayed on the planar image display device 12 may be displayed on the planar image display device 12 by zooming or scrolling the stereoscopic image ( The entire image of the left-eye image 51a and the right-eye image 51b may not be displayed).

Specifically, as shown in FIG. 19, the stereoscopic image 61 is zoomed and scrolled so that the left-eye image 51a and the right-eye image 51b displayed on the planar image display device 12 may be zoomed and scrolled. . FIG. 19 is a diagram illustrating a state in which the left-eye image 51a and the right-eye image 51b displayed on the planar image display device 12 are zoomed and scrolled in response to the stereoscopic image 61 being zoomed and scrolled. In FIG. 19, when the stereoscopic image 61 is zoomed and scrolled, a part of the left-eye image 51 a and the right-eye image 51 b are displayed on the flat image display device 12 in a semi-transparent manner. Specifically, in FIG. 19, a part of the part where the left-eye image 51 a and the right-eye image 51 b overlap and a part of the part which does not overlap are displayed on the screen of the flat image display device 12. In addition, a stereoscopic image corresponding to a part of a portion where the left-eye image 51 a and the right-eye image 51 b overlap is displayed on the screen of the stereoscopic image display device 11. As shown in FIG. 19, the left-eye image 51 a and the right-eye image 51 b displayed on the flat image display device 12 are magnified at the same ratio as the magnification ratio of the stereoscopic image 61. Since the screen of the stereoscopic image display device 11 is larger than the image display area 50 of the flat image display device 12, the imaging target image 63 is displayed larger than the imaging target images 53a and 53b. Further, the left-eye image 51a and the right-eye image 51b displayed on the flat image display device 12 are scrolled in response to the stereoscopic image 61 being scrolled. That is, the image displayed on the flat image display device 12 is the same image as the image displayed on the stereoscopic image display device 11. Thus, similarly to the stereoscopic image displayed on the stereoscopic image display device 11, the planar image displayed on the planar image display device 12 is also zoomed and / or scrolled, so that the correspondence between the stereoscopic image and the planar image for the user can be achieved. Becomes easier to understand.

  In the above embodiment, the planar image display device 12 displays an image obtained by superimposing the left-eye image 51a and the right-eye image 51b in a translucent manner. In another embodiment, any display may be used as long as the user can recognize the shift (the shift in position, size, and rotation) between the left-eye image 51a and the right-eye image 51b. For example, the outlines of the two images may be highlighted so that the user can recognize them, and the two images may be superimposed and displayed without being translucent. That is, one image may be displayed so that a part of the other image is completely hidden.

  Further, the position, size, or rotation of the left-eye image 51a and / or the right-eye image 51b is not limited to the above-described operation, and may be adjusted by any operation. For example, a button (a cross button or the like) may be disposed on the lower housing 13b, and the position of the left-eye image 51a and / or the right-eye image 51b may be adjusted by operating the button. Specifically, for example, when an image to be moved is selected using the stick 16 and the right button of the cross button is pressed, the selected image is moved to the right and the left button is pressed. May move the selected image to the left. Also, for example, an image to be rotated is selected using the stick 16, the selected image is rotated clockwise when the right button of the cross button is pressed, and is selected when the left button is pressed. The rotated image may be rotated counterclockwise. Also, for example, an image to be enlarged or reduced is selected using the stick 16, and the selected image is enlarged when the up button of the cross button is pressed, and is selected when the down button is pressed. The image may be reduced.

  In this embodiment, the case where a display capable of stereoscopic display with the naked eye is used has been described. However, even when stereoscopic display is performed using glasses such as a time-division method, a deflection method, and an anaglyph method (red and blue glasses method). The present invention is applicable.

(Second Embodiment)
Next, a second embodiment will be described. In the second embodiment, the image display device 10 described above also operates as a game device. The lower housing 13b of the image display apparatus 10 according to the second embodiment is provided with a plurality of operation buttons (a cross button and other buttons) operated by the user.

  The image display apparatus 10 according to the second embodiment operates in the first mode and the second mode. The first mode is a mode in which a stereoscopic image is displayed on the stereoscopic image display device 11 using images captured by the left eye image capturing unit 18a and the right eye image capturing unit 18b as in the first embodiment. The second mode is a mode in which a stereoscopic image is displayed in real time on the stereoscopic image display device 11 using an image captured by the virtual stereo camera. In the second mode, an image obtained by capturing the virtual space with the virtual stereo camera (the left-eye virtual camera and the right-eye virtual camera) is displayed on the stereoscopic image display device 11. In the second mode, the virtual stereo camera captures a three-dimensional virtual space, thereby generating a left-eye image and a right-eye image having a predetermined parallax. The image display device 10 displays a stereoscopic image on the stereoscopic image display device 11 in real time by combining the left eye image and the right eye image obtained by capturing the virtual space in real time.

  In the second mode, for example, a role-playing game in which a story progresses while a player character operated by a user explores a three-dimensional virtual space is assumed. In the role playing game, various game scenes (for example, a scene where the player character explores the cave, a scene where the player character explores the forest, etc.) are prepared in advance. The virtual stereo camera is set in advance according to various game scenes (zoom setting, focus position setting, distance setting between the left-eye virtual camera and the right-eye virtual camera, etc.). For example, in a scene for exploring a cave, the distance between the left-eye virtual camera and the right-eye virtual camera is set to a first distance in advance, and in a scene for exploring a forest, the distance between the left-eye virtual camera and the right-eye virtual camera. Is preset to the second distance.

  The distance between two virtual cameras (the left-eye virtual camera and the right-eye virtual camera) is the depth direction of various three-dimensional objects (for example, rock objects and tree objects) existing in the three-dimensional virtual space. Affects. For example, when the distance between two virtual cameras is relatively long, when a three-dimensional object is imaged, a stereoscopic image in which the depth direction of the three-dimensional object is longer is displayed. The distance between the two virtual cameras is predetermined by the game designer according to each scene of the game.

  Here, in the second embodiment, the distance between the two virtual cameras is adjusted according to the position of the hardware slider 14 (see FIG. 1) of the image display apparatus 10. That is, the user of the image display device 10 can adjust the distance between the two virtual cameras using the hardware slider 14 so that the stereoscopic image is easier to see for the user. Specifically, for example, when the position of the hardware slider 14 is located at the center of the movable range, the distance between the two virtual cameras is set to a predetermined value (default value). For example, when the hardware slider 14 is located at the right end, the distance between the two virtual cameras is set to 125% of the default value. For example, when the hardware slider 14 is located at the left end, the distance between the two virtual cameras is set to 75% of the default value.

  As described above, in the second embodiment, the user can adjust the distance between two virtual cameras using the hardware slider 14. Thereby, the appearance of the stereoscopic image can be adjusted.

  In the first mode, since the distance between the left-eye image capturing unit 18a and the right-eye image capturing unit 18b cannot be adjusted, the hardware slider 14 switches whether to display a stereoscopic image on the stereoscopic image display device 11. Used as In the first mode, for example, when the position of the hardware slider 14 is at the right end, a stereoscopic image is displayed on the stereoscopic image display device 11, and when the position of the hardware slider 14 is at the left end, the stereoscopic image display device 11 is displayed. Is not displayed. When a stereoscopic image is not displayed on the stereoscopic image display device 11, no image may be displayed on the stereoscopic image display device 11, or a planar image may be displayed.

  Next, details of processing performed in the image display apparatus 10 according to the second embodiment will be described. First, main data stored in the main memory 31 during the processing will be described. FIG. 20 is a diagram illustrating a memory map of the main memory 31 of the image display apparatus 10 according to the second embodiment. As shown in FIG. 20, the main memory 31 is provided with a data storage area 80. The data storage area 80 stores virtual camera data 81, operation data 82, character data 83, and the like. In addition to these data, the main memory 31 stores a program for executing the above processing, image data of various objects appearing in the game, and the like.

  The virtual camera data 81 is data relating to the setting of the virtual stereo camera existing in the game space. The virtual stereo camera settings include the distance between the left-eye virtual camera and the right-eye virtual camera of the virtual stereo camera, the zoom setting of the virtual stereo camera, the position of the gazing point of the virtual stereo camera, and the like.

  The operation data 82 is data indicating input to the plurality of operation buttons (not shown). When each operation button is pressed by the user, data indicating that each operation button has been pressed is stored in the main memory 31.

  The character data 83 is data relating to a player character that exists in the game space and is operated by the user, and includes the position of the player character in the game space and the characteristic information of the player character.

  Next, details of the processing according to the second embodiment will be described with reference to FIG. FIG. 21 is a main flowchart showing details of the processing according to the second embodiment. When the power of the image display device 10 is turned on, the CPU 30 of the image display device 10 executes a startup program stored in the ROM 32, whereby each unit such as the main memory 31 is initialized. Next, the program stored in the ROM 32 is read into the main memory 31, and the CPU 30 starts executing the program. The program may be stored in the storage data memory 34 or may be provided to the image display device 10 via the communication module 35. The flowchart shown in FIG. 21 is a flowchart showing a process performed after the above process is completed. In FIG. 21, description of processing that is not directly related to the present invention is omitted. Further, the processing loop of step S52 to step S56 shown in FIG. 21 is repeatedly executed for each frame (for example, 1/30 second, referred to as frame time).

  First, in step S51, the CPU 30 determines whether or not the first mode is selected. Specifically, the CPU 30 displays a screen that allows the user to select the first mode or the second mode on the flat image display device 12, and detects an input from the user. When the first mode is selected by the user, the CPU 30 next executes a process of step S57. On the other hand, when the second mode is selected by the user, the CPU 30 next executes a process of step S52.

  In step S <b> 52, the CPU 30 sets the distance between the left-eye virtual camera and the right-eye virtual camera according to the position of the hardware slider 14. Specifically, the CPU 30 detects the position of the hardware slider 14, calculates the distance between the two virtual cameras, and stores it in the main memory 31 as virtual camera data 81. Next, the CPU 30 executes a process of step S53.

  In step S53, the CPU 30 acquires operation data. Specifically, the CPU 30 refers to the main memory 31 and acquires operation data regarding a plurality of operation buttons. Next, the CPU 30 executes the process of step S54.

  In step S54, the CPU 30 executes a game process. Specifically, the CPU 30 updates the position of the player character in the game space or causes the player character to perform a predetermined action based on the operation data acquired in step S53. Further, the CPU 30 causes an object other than the player character existing in the game space to execute a predetermined action. Further, the CPU 30 updates the position of the gazing point of the virtual stereo camera or updates the zoom setting. Next, the CPU 30 executes a process of step S55.

  In step S <b> 55, the CPU 30 displays a stereoscopic image on the stereoscopic image display device 11. Specifically, the CPU 30 captures the game space with a virtual stereo camera, and acquires a left-eye image and a right-eye image. Then, the CPU 30 combines the left-eye image and the right-eye image to generate stereoscopic image data, and causes the stereoscopic image display device 11 to display the stereoscopic image. Next, the CPU 30 executes a process of step S56.

  In step S56, the CPU 30 determines whether or not the game is over. For example, the CPU 30 determines whether or not the user has pressed a button for instructing the end of the game (one of a plurality of operation buttons). When the determination result is negative, the CPU 30 executes the process of step S52 again. If the determination result is affirmative, the CPU 30 ends the process shown in FIG.

  In step S57, the CPU 30 executes processing in the first mode. The process in step S57 is the same as the process in the first embodiment (steps S1 to S8 in FIG. 14), but between step S5 and step S6 in FIG. 14, as shown in FIG. The determination process of S58 is performed. FIG. 22 is a flowchart showing details of processing in the first mode. In step S58, the CPU 30 determines whether or not the position of the hardware slider 14 is a predetermined position (for example, the right end). If the determination result is affirmative, the CPU 30 next executes a process of step S6. If the determination result is negative, the CPU 30 next executes a process of step S7.

  As described above, in the second embodiment, the image display device 10 includes the first mode in which a stereoscopic image is displayed using the left-eye image and the right-eye image that have already been captured, and the virtual that exists in the virtual space. The operation is performed in the second mode in which a stereoscopic image is displayed using the left-eye image and the right-eye image captured by the stereo camera.

  In the first mode, the left-eye image and right-eye image may be images captured by the stereo camera 18 (the left-eye image capturing unit 18a and the right-eye image capturing unit 18b), or may be captured by another stereo camera. It may be an image. In the first mode, since an already captured image is used, the parallax caused by the distance between the left eye image capturing unit 18a and the right eye image capturing unit 18b cannot be changed. Therefore, in the first mode, the hardware slider 14 functions as a switch for switching between displaying and not displaying a stereoscopic image. Thereby, the user can switch ON / OFF of the stereoscopic display using the hardware slider 14.

  On the other hand, in the second mode, the left-eye image and the right-eye image are images captured by the virtual stereo camera (the left-eye virtual camera and the right-eye virtual camera). The distance can be arbitrarily changed. In the second mode, the hardware slider 14 is used to change the distance between the virtual cameras (the distance between the left-eye virtual camera and the right-eye virtual camera). Therefore, the user can adjust the appearance of the stereoscopic image. Further, since the distance between the virtual cameras can be changed from the default value according to the position of the hardware slider 14, the user does not need to adjust the hardware slider 14 according to the game scene. That is, the default value of the distance between the virtual cameras set in each game scene is a value determined by the designer, and the stereoscopic image captured with such virtual camera settings is uncomfortable for all users. It is not always a stereoscopic image. For example, for a certain user, it may be easier to view a stereoscopic image when the distance between virtual cameras is set to 80% of the default value in each game scene. Therefore, it is not necessary to adjust the position of the hardware slider 14 in each game scene by setting the ratio of the distance between the virtual cameras to the default value according to the position of the hardware slider 14.

  In the second mode, the horizontal shift between the left-eye image and the right-eye image may be set according to the position of the hardware slider 14. That is, instead of adjusting the distance between the virtual cameras, the horizontal shift between the left-eye image and the right-eye image may be adjusted according to the position of the hardware slider 14.

  Also in the second mode, the shift (lateral shift) between the left-eye image and the right-eye image may be adjusted using the position adjustment bar 54 as in the first embodiment. Accordingly, the user can move a predetermined object existing in the game space in a direction perpendicular to the screen of the stereoscopic image display device 11.

  In the first and second embodiments, the portable image display device 10 including both the stereoscopic image display device 11 and the flat image display device 12 is assumed. In other embodiments, these devices may be configured as separate devices and they may be connected. For example, a first display device capable of stereoscopic display, a second display device that performs only planar display, and a control device that performs the above-described processing may be configured as separate hardware. Then, these devices may function as an image display control system by being connected to each other by wire or wirelessly.

  In another embodiment, a display device capable of simultaneously setting a stereoscopic display region for performing stereoscopic display and a planar display region for performing planar display is used as the stereoscopic image display device 11 and the planar image display device 12. Also good. That is, the stereoscopic display area of such a display device may be used as the stereoscopic image display means, and the flat display area may be used as the flat image display means.

  In other embodiments, the above adjustment is also applied to an arbitrary information processing apparatus (for example, a PDA (Personal Digital Assistant), a mobile phone, etc.) having a display device and a touch panel, or a personal computer having a pointing device such as a mouse. A method may be applied.

  In the above-described embodiment, the adjustment of the stereoscopic image (adjustment of the positions of the left-eye image and the right-eye image), the zooming and scrolling of the stereoscopic image, and the like are performed by the operation using the touch panel. In other embodiments, a stereoscopic image may be adjusted by operating a pointing device such as a mouse. For example, the slider of the position adjustment bar displayed on the screen may be adjusted by operating the mouse.

  Moreover, in the said embodiment, the process by the flowchart mentioned above was performed because CPU30 of the image display apparatus 10 performed a predetermined | prescribed program. In another embodiment, part or all of the above processing may be performed by a dedicated circuit included in the image display device 10. For example, a dedicated GPU (Graphics Processing Unit) for generating an image to be displayed on the stereoscopic image display device 11 may be provided.
